Exploring Allegiant's Reservation Management Tools

Navigating Allegiant Reservation Challenges

⚠️ Cannot access reservation or find confirmation.

Cause: Incorrect entry, email missing, or not logged into an account.

Solution: First, double-check your confirmation number and last name for typos. If using a payment card, ensure the last four digits and departure date are accurate. Check your email's spam or junk folder for the original confirmation. If you booked without logging into an Allways Rewards® account, try to access it via 'Manage Trip' directly, not through your account dashboard. If your trip was booked through your account, ensure you are logged in. If issues persist, contact Allegiant Customer Care.

⚠️ Forgot Allegiant account password.

Cause: Loss of login credentials for your Allways Rewards® account.

Solution: On the sign-in page, click the 'Forgot Password?' link. Enter the email address associated with your account. Allegiant will send an email with a temporary password or a password reset link. Remember to check your spam or junk mail folders if you don't see it immediately. We know being locked out is stressful; this is often the fastest fix.

⚠️ Website or mobile app technical glitches.

Cause: Browser issues, app malfunction, or temporary system errors.

Solution: If you're encountering technical problems with the website or app, first try clearing your browser's cache and cookies or restarting the app. You can also try accessing the portal from a different device or web browser. Ensure your device has JavaScript and cookies enabled for optimal performance. If the problem continues, contact Allegiant's Customer Care for assistance.

Quick Answers for Your Allegiant Reservations

Q: How do I find my Allegiant Air reservation if I don't have the confirmation email?

You can retrieve your reservation by visiting the 'Manage Trip' section on allegiantair.com. You will need to provide the last name of a passenger and either your confirmation number or the last four digits of the payment card used for the booking along with the departure date.

Q: Can I change my Allegiant Air flight dates or destination?

Yes, you can change your flight dates or destination through the 'Manage Trip' portal. Please note that change fees may apply unless you purchased Trip Flex™ travel protection at the time of booking. Any difference in airfare will also be applied.

Q: What is Allegiant's cancellation policy?

Allegiant offers a full refund for cancellations made within 24 hours of booking, provided the scheduled departure is at least one week away. After this period, tickets are generally non-refundable, but you may receive an Allegiant credit voucher for future travel, minus any applicable fees. Trip Flex™ can waive these fees for one change or cancellation.

Q: How do I check in for my Allegiant flight online or using the app?

You can check in online via allegiantair.com or through the Allegiant mobile app starting 24 hours before your scheduled departure and up to 45 minutes prior. During this process, you can verify seat assignments and baggage, and receive your mobile or printable boarding pass.

Q: Do I need to confirm my Allegiant reservation 24 hours prior to departure?

No, you do not need to confirm your reservation 24 hours prior to departure. However, all passengers must check in and obtain a boarding pass before their flight. Online check-in opens 24 hours before departure.

Q: Can I choose my seat when booking with Allegiant?

Yes, you can select your seat for a nominal fee during the initial booking process or later through the 'Manage Trip' section. If you do not pre-purchase a seat, one will be assigned to you automatically during the online check-in window, which opens 24 hours prior to departure.
